SELF-POWERED ADAPTER CARTRIDGE FOR TAPE PLAYERS BACKGROUND OF THE INVENTION This invention relates generally to adapter cartridges for insertion into tape players, and has particular utility in connection with adapter cartridges of the type housing a small radio therein to convert the tape player to a radio receiver unit.
Heretofore, adapter cartridges have been provided which contain radio receiver units within the cartridge to be inserted into a tape player in the place of a conventional tape cartridge. The adapter cartridge so inserted then converts the tape player to a radio receiver. These adapters include a self-contained battery within the adapter cartridge which serves to power the radio. The battery within the cartridge deteriorates even when the adapter cartridge is not used. Therefore, it may occur that the battery will become inoperative at an inopportune moment when it is desirous to play the radio.
SUMMARY OF THE INVENTION An object of this invention is to provide an adapter cartridge for insertion into a tape player which includes means to BRIEF DESCRIPTION OF THE DRAWINGS Like reference numerals throughout the various views of the drawings are intended to designate the similar elements or components.
FIG. 1 is a plan view of an adapter cartridge constructed in accordance with this invention showing portions thereof broken away and engaged with a tape player of which only a fragmentary portion is illustrated;
FIG. 2 is a fragmentary portion of an alternate form of adapter cartridge constructed in accordance with this invention;
FIG. 3 is an elevational sectional view of yet another alternate form of adapter cartridge constructed in accordance with this invention; and
FIG. 4 is yet another alternate form of adapter cartridge constructed in accordance with this invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Seen in FIG. 1 is an adapter cartridge designated generally by reference numeral I0 and which contains a power utilization device 12, preferably, a small AM or F M or AM-FM radio receiver. The adapter cartridge includes a power generator 14 drivingly coupled to a capstan drive 16 mounted within a tape player 18, only a portion of which is illustrated herein.
The output of the radio 12 is coupled to a transducer device 13 which, in turn, is positioned in abutting relationship with the magnetic tape head 15 of the tape player 18 to induce audio signal information into the tape head for reproduction of the signals received by the radio in the audio portion of the player. Standard control knobs 20 and 22 are provided on the radio.
In the embodiment illustrated in FIG. I, a pulley drive wheel 24 is mounted for rotation adjacent an opening 25, and the periphery of the drive wheel 24 is exposed through this opening to engage the capstan 16. A pulley or O-ring drive belt 26 is wrapped about a portion of the drive wheel 24 and extends therefrom to engage with a reduced inner diameter pulley portion of a pulley wheel 28. The major diameter portion of the pulley wheel 28 receives a second pulley or Oring drive belt 30 which, in turn, wraps about a small pulley 32 secured to a drive shaft 33 extending from the generator 14. In the illustrated arrangement, the drive shaft 33 of the generator I4 will rotate at approximately 1,000 r.p.m. to produce i-watt-maximum power, which is more than sufiicient to operate the radio receiver 12. Thus there is a substantial step-up from the r.p.m. of the capstan 16. The voltage output of the generator 14 is substantially constant as governed by the constant speed of rotation of the capstan shaft 16. Typically, the voltage regulation of a generator used in accordance with this invention may be constant within 1 percent.
FIG. 2 illustrates an alternate form of drive coupling between the generator shaft 330 and the capstan 16. Here a drive friction wheel 36 is rotatably secured within the adapter cartridge and engages the capstan I6 as illustrated. The drive wheel 36 engages a reduced diameter portion 38a of a larger idler wheel 38. The peripheral portion of the idler wheel 38 engages a small drive wheel 40 located at the end of the shaft 33a on a generator 14a. Here, the small friction wheel 40 engages the top surface of the idler wheel 38 to drive the generator thereby producing a voltage output therefrom.
FIG. 3 illustrates still another alternate form of this invention and shows a friction drive wheel 42 engaged with the capstan shaft 16 and with a reduced diameter portion 44a of a friction idler wheel 44. The peripheral portion 44b of the friction wheel 44 is beveled to conform and engage with a correspondingly beveled friction wheel 46 secured to the output shaft 33b of a generator 14b. The generator 14b has the electrical output thereof coupled to the power utilization means within the adapter cartridge 10b. In the embodiments illustrated in FIGS. 1, 2 and 3, the ratio between the capstan I6 and the generator shaft 33, 33a, 33b is a step-up ratio of about 18 to I, it being understood that any suitable ratio may be used.
FIG. 4 illustrates still another form of this invention. Here the generator 14c is directly driven by the capstan shaft I6 by means of a friction wheel 50 coupled directly to the shaft 33c of the generator Me. This arrangement is possible where the capstan shaft 16 rotates at a sufficiently high speed or where the generator 14c is of the type to produce a sufficient output voltage at low speeds.
What has been described is a simple and efficient means for providing power within an adapter cartridge to be developed only during periods of time when the cartridge in inserted into a tape player, such power being developed as a result of mechanical power taken from the capstan of the tape player.
Accordingly, variations and modifications of this invention may be effected without departing from the spirit and scope of the novel concepts disclosed and claimed herein.
